This paper characterizes status quo rules in the binary social choice environment. We consider the full preference domain which allows for indifference. We show that status quo rules are the only rules that satisfy ontoness, strategy-proofness and a solidarity property. The solidarity property that we consider, positively correlates the welfare of a voter to rest of the voters in case of her improvement. It is independent from the usual solidarity axiom of welfare dominance under preference replacement used in the literature. © 2020 Elsevier B.V.
